Remarks

The SetROP2 function sets the current foreground mix mode. GDI
uses the foreground mix mode to combine pens and interiors of
filled objects with the colors already on the screen. The
foreground mix mode defines how colors from the brush or pen and
the colors in the existing image are to be combined.
